Product
Sun StorageTek 5310 NAS Appliance
Sun StorageTek 6130 Array

Bug Id
<SUNBUG: 6254438>

Date of Resolved Release
11-MAY-2007

Impact

Insertion or removal of a RAID controller as part of routine maintenance activity on Sun StorEdgeTek 5310 or 6130 arrays may cause the alternate controller in the same tray to boot, causing a complete loss of access to the array until the alternate boots up.


Contributing Factors

This issue can occur on the following platforms:

  • Sun StorEdgeTek 6130 without firmware 6.12.03.12
  • Sun StorEdgeTek 5310 without patch 119351-04

To determine the version of firmware on the system, the sscs(1M) command can be run as in the following example:

    # /opt/se6x20/cli/bin/sscs list array <array name>
    Array: <array name>
    Array Type:                6130
    Serial Number:             SUN.54062390150.0440AWF007
    Firmware Version:          06.19.23.10

    ...


Symptoms

This issue presents itself during ordinary replacement of a controller or during the replacement of a cache battery during normal maintenance.

Data hosts using the impacted arrays will see evidence of a loss of access in the host messages file. The messages vary from platform to platform, but will indicate:

  • SCSI retries
  • Fibre Channel resets
  • Devices disappearing from the Fibre Channel switch fabric

Management hosts attempting get status information from the array may get a communication error. Communications errors may present themselves during any activity. These lapses in managing the array are brief(up to 2 minutes), as the booting controller will allow management access as it finishes booting.

For 5310 and 5320 NAS Appliances, users will be unable to access shares or NFS export filesystems.


Workaround

To avoid this issue (for systems without the current firmware), it is recommended that any activity requiring maintenance of the array controller or array controller cache battery be considered an offline operation. As such, these types of maintenance activities should be performed during an outage of all data services provided by the array.


Resolution

This issue is addressed on the following platforms:

  • Sun StorEdgeTek 6130 with firmware 6.12.03.12 or later
  • Sun StorEdgeTek 5310 with patch 119351-04 or later

Note: The above firmware revision is bundled with Sun StorEdge 6130 Array Configuration Services 1.2 or later software. It is recommended that customers upgrade the management host to Common Array Manager (CAM) 5.1 or later, along with the firmware bundled within it (6.19.25.10).

Common Array Manager (CAM) 5.1 is available for download at
